Fujitsu’s feely Fujitsu showed a prototype tablet that uses ultrasound to let users feel realistic textures of images displayed on the screen. The ultrasound technology changes the friction between the user’s fingers and the touchscreen surface. To create a floating, slippery effect, the tablet generates a high-pressure air layer just above the screen. To create a bumpy or rough effect, the device generates high- and low-friction zones through ultrasonic vibrations. At MWC, the prototype gives users the sensation of plucking the strings of a koto, a traditional stringed instrument from Japan. No anticipated release date.
